Our yard is pretty well qualified, with native plants, rain water catchment, gray water, chickens, bees, food production, and landscaping with salvaged materials. We've been told to expect over 500 people (and perhaps well over that, since registration has been particularly strong so far). There's also a need for volunteers to help out, so sign up if you're interested.
Here's a fuller description of the tour from StopWaste: "The 7th annual tour continues to celebrate the diversity of Bay-Friendly gardens. Urban farmers grow abundant harvests of fruit and vegetables, and keep chickens and bees. Native plant enthusiasts embrace the local flora. Salvaged material aficionados blend recycled art into the landscape. Bay-Friendly gardens offer something for everyone—come and discover ideas for creating your perfect haven.... Gardens range from professionally designed postage stamp-sized lots in Berkeley to exuberant one-acre market gardens in Pleasanton."
We're pretty excited, although we have a bit more prep to do over the next few weeks.
